Plasma display device

Abstract

A plasma display device is disclosed. In one embodiment, the plasma display device includes a plasma display panel (PDP), a chassis base having one side for supporting the PDP, and a printed circuit board assembly (PBA) mounted on another side of the chassis base. The chassis base includes a main frame mounted on the PDP, a bracket mounted on the main frame, a sub-frame mounted on at least one of the main frame, the bracket, and the PDP, and a shield box that is mounted to at least one of the main frame, the bracket, and the sub-frame, and that includes the PBA. One embodiment reduces weight of a chassis base and manufacturing cost, and improves impact resistance of a PDP.
